Table 3.
Distributions of tropical cyclone characteristics in the IBTrACS and STORM datasets per basin. The time period 1980–2018 is used for the IBTrACS dataset (38 years of data). For the STORM dataset, we calculated the mean and standard deviation (between brackets) for a random selection of 1000 times 38 years of data. The n-value is given as the second number between brackets.
